The dark side of India's tea industry

Indians are the world's biggest tea drinkers and producers. Half of the country's entire output comes from the north-eastern state of Assam, but the conditions for many of those who work on its tea plantations are appalling. Workers earn well below the minimum wage and malnutrition is also common. Laws about facilities and conditions on tea estates exist, but many don't comply. Our correspondents Natacha Butler and Vikram Singh went to visit one such estate in the south of Assam.
